Compiler Design Project How to Compile the Source Code Run the Makefile in the root directory and ./compiler executable will be built. How to Compile the Sample Program Run run.sh or ./compiler < input.txt > out.c 2> err.log. This will generate a C program named out.c and show any compilation errors in err.log. Run gcc -o program out.c to compiler the generated program. Test the generated program by running ./program.
